Ultra-photorealistic portrait of a real human, with extremely realistic facial detail and true-to-life skin rendering. Natural human skin with visible pores, fine micro-texture, subtle wrinkle density, realistic under-eye texture, faint freckles, tiny moles, slight redness variation around the nose and cheeks, natural tonal unevenness, and accurate skin roughness with soft specular behavior. Skin must show soft subsurface scattering so light passes naturally through thin areas of the face, avoiding any waxy or plastic appearance.

Eyes must look biologically real: detailed iris pattern, layered iris color variation, realistic pupil size, transparent wet cornea, soft limbus ring, natural sclera tint, subtle tiny veins in the sclera, and soft shadowing where the eyelids meet the eye. The eyes should have realistic depth, moisture, and refraction, not flat or painted-looking eyes.

Eyebrows must be highly realistic with individual visible hairs, natural strand direction, slight asymmetry, varied density, a believable hairline, and soft transitions into the skin. No stamped or overly perfect brows.

Hair must look like real human hair with individual strands, natural strand grouping, slight flyaways, believable volume, varied thickness, subtle translucency, and realistic specular highlights. Hair should not appear helmet-like, overly smooth, or like a single plastic mass.

Facial hair must be realistic and detailed: visible stubble or beard texture, individual whiskers, natural density variation, slight patchiness where appropriate, soft transitions at the cheeks and neckline, realistic follicle detail, and subtle peach fuzz on the skin where visible. Facial hair should integrate naturally into the skin rather than looking pasted on.

Professional photographic realism, natural light behavior, realistic depth of field, lifelike color response, crisp but natural detail, no beauty-filter effect, no over-smoothing, no artificial airbrushing, no CGI look.
